Job Title: Senior Software Engineer (With Machine Learning Experience)
Job Description:
We are seeking a skilled and motivated Python Engineer with 5+ years of professional experience, including at least 2 years of hands-on experience in Machine Learning (ML). The ideal candidate will possess strong Python development skills, a deep understanding of object-oriented programming (OOP), and practical experience with NoSQL databases, especially MongoDB. Familiarity with cloud platforms such as AWS, GCP, or Azure is also required.
This role is perfect for a developer who is not only proficient in backend engineering but also enthusiastic about applying ML concepts in real-world applications. You'll work closely with cross-functional teams to develop and optimize scalable, reliable, and maintainable Python-based solutions.
Responsibilities :
- Design, develop, and maintain Python applications with a focus on performance and scalability.
- Design systems with non-linear time complexity and efficient space usage across compute and storage. Ensure stateless, idempotent request processing with no in-memory state. Model schemas for future evolution, supporting increasing data volume and structural changes.
- Build and operate cloud-based SaaS applications with a focus on production reliability. Design includes not only functional code but also integrated monitoring, alerting, and health checks to ensure observability and operational excellence in a multi-tenant environment.
- Apply object-oriented programming (OOP) principles to craft reusable, modular code.
- Develop, implement, and optimize machine learning models in production environments.
- Leverage NoSQL databases like MongoDB for efficient data storage and retrieval.
- Work with cloud platforms (AWS, GCP, Azure) for application deployment and data services.
- Write and maintain robust unit and integration tests using test-driven development (TDD) practices.
- Participate in the full software development lifecycle - from requirements gathering to deployment.
- Collaborate with cross-functional teams, participate in Agile ceremonies, and contribute to technical discussions.
- Engage in code reviews and mentor junior team members where appropriate.
- Stay updated with emerging trends in Python development, machine learning, and software engineering best practices.
Requirements:
- Bachelor's degree in Computer Science, Engineering, or a related field.
- 5+ years of professional experience in Python development.
- At least 2 years of hands-on experience with Machine Learning (model development, evaluation, and deployment).
- Strong understanding of OOP principles and real-world software design.
- Experience working with NoSQL databases, particularly MongoDB.
- Familiarity with TDD practices and writing unit tests.
- Practical experience with cloud platforms (AWS, GCP, or Azure).
- Proficiency with version control systems such as Git.
- Excellent problem-solving and debugging skills.
- Strong communication and teamwork abilities.
- A proactive, self-motivated attitude with a passion for continuous learning.
Preferred Qualifications:
- Hands-on experience in AI concepts including LLMs, prompt engineering, or traditional AI.
- Strong grasp of supervised, unsupervised, and reinforcement learning with practical experience in key ML algorithms (e.g., regression, SVMs, neural networks, clustering). Proficient with ML frameworks like scikit-learn, TensorFlow, PyTorch, and XGBoost. Solid foundation in math (linear algebra, calculus, probability, statistics) and understanding of optimization and loss functions. Experience with model serving using Flask, FastAPI, or TensorFlow Serving.
- Experience with Python ML libraries such as scikit-learn, TensorFlow, PyTorch, or similar.
- Knowledge of Agile/Scrum methodologies and collaborative development workflows.
What We Offer:
- A collaborative and innovative team environment.
- Opportunities to work on AI/ML-powered products and projects.
- Ongoing learning and career development opportunities.
- A dynamic culture focused on growth, curiosity, and problem-solving.
